It was clear based on the game release schedule that the 3DS was Nintendo's focus in 2013. After reading this, it is even more clear. Wii U obviously underperformed drastically last year but the 3DS is the real reason for the current struggle.
They were clearly banking on 3DS to Make up for the Wii U delays. Once they realized that HD development had pushed back Wii U plans they needed 3DS to more than make up for it.
Instead, it failed big time. (At that purpose)
